Circadian rhythm isn’t just controlled by your brain. Every cell in your body runs on a 24-hour cycle, including your muscle cells.
Karyn Esser is the chair of the department of physiology and aging at the University of Florida, and she’s a leading expert on circadian rhythm in muscle cells. Karyn’s problem is this: How does the circadian rhythm in muscle cells change as we age, and how does exercise help keep our system in sync?
In this episode, Karyn explains:
- How every cell in your body has a clock in it
- How muscle clocks prepare cells for work and schedule recovery during rest
- How age affects these clocks’ ability to regulate effectively
- Why exercise can improve clock function
- Why jet lag and late-night eating can put your body clocks out of sync
